Lab Safety Supply 12K905 Filter Paper

This qualitative filter paper comes in a pack of 100 discs. Each disc measures 15 cm in diameter and uses cellulose material. It is rated for medium-slow porosity with an 8 micron pore size. The product meets FDA standards for laboratory use.

Build integration and workflow fit

The 0.17 mm thick discs handle both gas and liquid filtration tasks. No fluted design means flat contact with funnel surfaces. Grade 2 classification suits general qualitative analysis. The 100-count pack supports repeated testing without frequent reordering.

Suited for routine qualitative work

Technicians performing standard gravimetric analysis will find the medium-slow flow rate appropriate. Labs needing faster throughput or smaller pore sizes should evaluate other grades. The discs are not designed for quantitative ashless procedures. Applications requiring membrane or glass-fiber media need different products.

Questions about this item

At what pore size does the 8 µm cellulose disc start to restrict flow during prolonged filtration?

The uniform 8 µm pore size limits particle passage; flow rate declines as the medium loads with retained solids.

Does the 0.17 mm thick disc curl or release fibres when wet for an entire shift?

Cellulose construction stays flat and fibre-free during continuous liquid or gas contact.

Which funnel or holder diameter matches the 15 cm discs so they seal without bypass?

Use a 15 cm diameter funnel or filter holder to seat the discs flat and prevent edge leakage.
